Transportation of Payload Using Multiple Quadrotors via Rigid Connection
International Journal of Aerospace Engineering, 2022 Due to the limited payload capability of an aerial robot, multiple quadrotors can be used to manipulate payloads in aerial transportation, construction, and assembly tasks.

Distributed Collision-Free Motion Coordination on a Sphere: A Conic Control Barrier Function Approach [PDF]
, 2020 This letter studies a distributed collision avoidance control problem for a group of rigid bodies on a sphere. A rigid body network, consisting of multiple rigid bodies constrained to a spherical surface and an interconnection topology, is first ...

Modeling the kinematics and Dynamics of Compliant Contact [PDF]
, 2003 In this paper, we discuss the modeling of the kinematics and dynamics of compliant contact between bodies moving in Euclidean space. First, we derive the kinematic equations describing the motion of the contact point when two rigid bodies are rolling on ...

Ultra-fast escape maneuver of an octopus-inspired robot [PDF]
, 2014 We design and test an octopus-inspired flexible hull robot that demonstrates outstanding fast-starting performance. The robot is hyper-inflated with water, and then rapidly deflates to expel the fluid so as to power the escape maneuver.

A spatial impedance controller for robotic manipulation [PDF]
, 1997 Mechanical impedance is the dynamic generalization of stiffness, and determines interactive behavior by definition. Although the argument for explicitly controlling impedance is strong, impedance control has had only a modest impact on robotic ...

On Centroidal Dynamics and Integrability of Average Angular Velocity [PDF]
, 2017 In the literature on robotics and multibody dynamics, the concept of average angular velocity has received considerable attention in recent years. We address the question of whether the average angular velocity defines an orientation framethat depends ...

Dynamic whole-body motion generation under rigid contacts and other unilateral constraints [PDF]
, 2013 The most widely used technique for generating wholebody motions on a humanoid robot accounting for various tasks and constraints is inverse kinematics. Based on the task-function approach, this class of methods enables the coordination of robot movements

Quasi optimal sagittal gait of a biped robot with a new structure of knee joint [PDF]
, 2013 The design of humanoid robots has been a tricky challenge for several years. Due to the kinematic complexity of human joints, their movements are notoriously difficult to be reproduced by a mechanism. The human knees allow movements including rolling and

Quantifying the Evolutionary Self Structuring of Embodied Cognitive Networks [PDF]
, 2012 We outline a possible theoretical framework for the quantitative modeling of networked embodied cognitive systems. We notice that: 1) information self structuring through sensory-motor coordination does not deterministically occur in Rn vector space, a ...
